Hola, I am trying to map two fixed and known lenght lists into a hash, preferably without using variables.

I want to replace myfunc below with a short but legible bit of code, the last attempt below ends up using $_, @_ and %_ which is a bit mean.

Any better offers?? 

my @usual = qw ( data email stuff );   #--- fixed length

my $i = 0;
my %hash;

my @input = (
    #--- rather have no function
    { username => 'fred1', myfunc ( 12, 56, 78 ) },            
    #--- no use if have to reset $i
    { username => 'fnerk', map { $usual[ $i++ ] => $_ } (33, 44, 55) }
+,
    #--- hmm
    { username => 'aargh', map { @hash{@usual} = @$_; %hash } [ 33, 44
+, 55 ] },
    #--- longwinded
    { username => 'fnerk', map { $tmp = shift @usual; 
 push @usual,$tmp; $tmp, $_ } (33, 44, 55) },
    #--- heinous
    { username => 'aargh', map { @_{ @usual } = @$_; %_ } [ 33, 44, 55
+ ] },

);

sub myfunc {
    my %flib;
    @flib{ @usual } = @_;
    return %flib;
}

for ( @input ) {
    my %local = %$_;
    for (sort keys %local ) {
       print "key : $_ : val : $local{$_} : ";
    }
    print "\n";
}
